When these herdsmen began to gather in the pre-selected townships and began to gradually establish permanent gathering points, Tian Meng's side also began to prepare for the next step.

That's the infrastructure, and the question of pathfinding.

His Royal Highness wants to build a road on the grassland, so this road needs to be explored.

And connect the aggregation points one by one, at least most of the aggregation points.

After the implementation of the previous plan, there will be a large number of pastures in the entire grassland that no one grazes, and these grasslands will gradually begin to recuperate.

After all, the pastures of these herders are now strictly calculated to graze to the maximum extent without harming the pastures, and the Turks in the past could not have such a precise grazing range.

Therefore, after the integration, in fact, there are large areas of uninhabited land on the grassland of the entire Hanhai Prefecture.

In the future, these no-man's land can accommodate more herders, or carry out various policies such as rotational grazing.

Now, whether it's pathfinding or anything else, the most important thing is to start building the infrastructure first.

The infrastructure construction on the grassland, like the Tang Dynasty, is still very necessary to directly repair the official road. Many people think that the grassland does not need to build roads, and they think that the grassland roads are smooth and can be walked anywhere.

Just like the Inner Mongolia grassland in later generations, many people have the impression that there is no problem with driving for five minutes with their eyes closed.

Although this is the case, in fact, the current grassland of Hanhai Prefecture is far more lush than the grassland of later generations.

Why the Turks have a tribe called the Gaoche tribe, because they are good at building high-chariots, the so-called high-chariots are very similar to the Mongolian Lele chariots, the wheels are very tall, because the pastoral area is knee-high snow in winter, the grass is deep in summer, and there are some swamps, so after the wheels are big, it can easily walk on the grassland.

But before building a road, the most important thing is to connect all the existing gathering points.

Connecting these gathering points and guiding the way in the vast grassland is also very simple, pile up Ao Bao!

Well, according to His Highness's plan, the infrastructure of the steppe will start with a pile of Ao Bao!

Ao Bao, in later generations, is a symbol of sacrifice on the grassland, and in a certain period of time, it is also a symbol of some grassland nobles to show their wealth and power. But when it first appeared, it was a symbol of the grassland to show the border and guide the way.

The construction of roads on the grassland is not yet in turn, mainly because the grain cannot keep up, so this year we will start by piling up Ao Bao.

These packs are likely to serve as a guide for a long time to come.

In addition, in the early days of the grassland, there would be some sheep heads, cow heads and other animal skulls hung on them, and even dyed black or red, the main reason is that when the snow covers the winter heavy snow, you can find the traces of the Ao Bao from a long distance.

Because if you pile up stones, the grassland is covered with heavy snow in winter, and it is impossible to distinguish Ao Bao when it is far away, and the leather materials of cattle and sheep are often important warm materials and cannot be wasted.

The skulls of cattle and sheep can sometimes be used for this purpose.

But in the current Datang, because there is no shortage of cloth, it can directly replace these animal skulls with cloth for the time being, after all, cloth can be made larger.

The early Ao Bao was also not round, but had a different shape to indicate the direction.

Tian Meng is preparing to carry out this infrastructure construction activity on the grassland, which is different from Qinghai, where the grain is currently only transported to the first line of the Yinshan Mountains, so further north, it is better to simply use salt instead.

Because salt is more expensive than grain in the grasslands, it is more expensive to pay the herders for transporting a cart of salt in.

After finalizing the policy, Tian Meng directly began to extend the entire decree to the entire grassland.

All the roads are first checked with the herders to find the direction of the flat terrain, and then some of the higher slopes and other places are piled up with Ao Bao every about a kilometer or so.

The stones used in Ao Bao are loaded by herders on horseback from the nearby stone hills.

The shape of the whole Ao Bao will be set in different shapes, where there are no forks, they will be stacked into circles, and where there are forks, they will be set up as triangles or polygons, and the acute angles will indicate different directions.

And at each intersection, the name of the township in this direction, or the county seat, will be engraved on the stone tablet at the acute angle.

In addition, a five-pointed star will be inlaid with stones in the north direction of each Ao Bao, representing the direction of the North Star.

All the herdsmen who are willing to pile up the bags can get a pound of grain a day, or half a tael of salt. This price has been carefully calculated by Tian Meng, and it is lower than the current grain and salt prices on the grassland, not to mention that almost all herdsmen can do this work, regardless of age.

Nowadays, the herdsmen on the grassland do not do much work every day, and there is no other work except grazing, and grazing does not require all the people of a family to come out to graze.

At this time, they should find some work to do, as long as they can see the actual benefits, these herdsmen are the same as the ordinary people of Datang, and they can make their lives better, who doesn't want to?

Therefore, when Tian Meng began to spread the news to the large and small tribes of the grassland through the security army, the entire grassland was boiling.

Pile up Ao Bao, in order for them not to get lost on the grassland in the future, and still earn food and salt?! Isn't this pie in the sky? This was originally for the sake of them, the herdsmen living on the grassland, who should have been willing to work for nothing, but now they are willing to give them money?

My God, this must not be done until His Highness goes out of business? I heard that the political commissar and the officials of Datang who came to promote this policy said that Qinghai was built step by step in this way.

This good day is coming! Now not only do you have your own cattle and sheep, but Your Highness also has to build road signs on the grassland, and after the road signs are completed, you have to build a road along the road signs? With the road, the grain, salt, cloth, etc. from the outside world will enter the grassland and go deeper? Can they get these cheaper?

And also to sell useless wool to earn grain?

What else does this say?! Dry! That's it!

Especially when the Tang Dynasty soldiers or officials who were responsible for organizing the local herdsmen to pile up Ao Bao popularized some of the functions on the Ao Bao to all herdsmen, they were all stunned.

Sure enough, the Tang people are smart, and His Royal Highness, who can distribute cattle and sheep to them, is the embodiment of immortality, this Ao Bao has so many effects, why did they grassland people live on the grassland for so many years without thinking of it? Do you need to use experience to find your way?!

What else does this say?! it! One by one, the herdsmen left their homes with their horses, and they took the baskets they had woven and put them on horseback, and then loaded the gravel from the foot of the mountain, and then transported it to the calculated place to stack the bags and began to pile them up.

Soon, one by one, Ao Bao began to spread throughout the grassland like a sparkling fire.
